The operation of my invention will now be readily understood upon reference to the foregoingdescription and theaccompanying drawings, and it will be noted Vthat some change may be made in the detail construction and arrangement of the parts without departing from the spirit thereof-as, for instance, the outer ends of the water-tubes may be'provided with caps instead of plugs, and the upper head of the boiler may be substantially ilat instead of concave-convex, and that other minor changes may be made within the scope of the invention, the essential feature being to form the upper portion of the boiler larger than its base and to provide the side walls of the boiler with a series of substantially radial water tubes inclining downwardl7 from a horizontal plane.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. A steam-generator comprising a watercontaining,` shell having inclined side walls, and a series of water-tubes projecting from rroutes' said side walls at substantially right angles thereto and having their outer ends extended substantially equal distances from the center of the shell and closed.

2. A steam-generator consisting of a tapering water-containing shell having a series of Water-tubes arranged in rows one above the other and inclining outwardly and downwardly therefrom, the tubes of each row being gradually reduced in length from the bottom row upwardly.

The combination with a burner and a heater-jacket, of an inverted truncated conical shell having a series of radial water-tubes extended outwardly from and at right angles to the side Walls of the shell and closed at their outer ends, said outer ends being substantially equal distances from the center of the shell and disposed in a cylindrical plane parallel with the jacket.

In witness whereof I have hereunto set my hand this 23d day of February, 1901.

CHARLES A. KITTS.
